Pound Drops More Than in Week of Brexit Referendum: Chart

The pound fell the most this week since January 2009 after plunging as much as 6.1 percent on Friday to a 31-year low of $1.1841. The 4.8 percent weekly slide, prompted by growing concerns the U.K. is headed for a so-called hard Brexit and hastened by computer-initiated sell orders, just exceeds the drop during the week of the June 23 vote to quit the European Union.
